Trofim Lysenko

Trofim Denisovich Lysenko (Russian: Трофи́м Дени́сович Лысе́нко, Ukrainian: Трохи́м Дени́сович Лисе́нко, Ukrainian pronunciation: [troˈxɪm deˈnɪsowɪtʃ lɪˈsɛnko]; 29 September [O.S. 17 September] 1898 – 20 November 1976) was a Soviet agronomist and pseudo-scientist. He was a strong proponent of Lamarckism, and rejected Mendelian genetics in favour of his own idiosyncratic, pseudoscientific ideas later termed Lysenkoism.

In 1940, Lysenko became director of the Institute of Genetics within the USSR's Academy of Sciences, and he used his political influence and power to suppress dissenting opinions and discredit, marginalize, and imprison his critics, elevating his anti-Mendelian theories to state-sanctioned doctrine.

Soviet scientists who refused to renounce genetics were dismissed from their posts and left destitute. Hundreds if not thousands of others were imprisoned. Several were sentenced to death as enemies of the state, including the botanist Nikolai Vavilov. Lysenko's ideas and practices contributed to the famines that killed millions of Soviet people; the adoption of his methods from 1958 in the People's Republic of China had similarly calamitous results, culminating in the Great Chinese Famine of 1959 to 1962.
